Be it known that I, BIRGER JoHNsnN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles .and lState of California, have invented new. and

Yuseful Improvements in Dispensing Apparatus, of which cation.

This invention relates .to water carbonating apparatus, and has for an lobject to pro` vide an apparatus of simple and substantial construction and including one primary draft valve with a single operating lever whereby several desirable functions in the distribution of the liquids and gases in .the apparatus may be readily obtained. Y

the followingis a speciii- It is an object of the invention .to provide` a carbonating apparatus havingl ay water.

cooling chamber wherein water to be carbonated is chilled before it is saturated with carbonic lacid gas thus to secure an economy in the amount of gas absorbed as there isa greater coeiiicient ofsaturation .as the tem-4 perature of the water descends.

Another object is to provide means for the prevention of loss of trapped gas, means being provided to return the trapped gas tothe water-mainwhere it is returned with the water into the water cooling coil wherei-t is absorbed andloss is prevented.

Another object is to provide a carbonated..

water dispensing apparatus wherein means are provided for automatically admitting fresh water to the carbonator concurrently with the drawing of carbonated water; the

fresh supply being substantially equal to the amount of carbonated water drawn oil'. j Further, in this connection, it is an object to capacity for discharge of carbonated provide a carbonator having water, for instance several glasses, so that when a single glass or a couple of glasses of water aredrawn there isstilla charge of carbonated water in the carbonator and this ,charge is constantly replenished as carbon-c` trated in F ig; 2 in the second position; and..

of a positive valve shut-off. Another object is to use a single medium as a gas inlet and as a carbonatedwater discharge, the alternate use of which is controlled bythe single Y means draft valve. v f

Another object is to -providefor the disfharse ef air that may ,formfreni-water trated` i in the pipe, this accumulated by the draft valveas initial portionV of trapped in the outlet air being discharged it passesthrough the opening movement.` v

Further, anobject is to provide for the. use of the main draft valve to secure a dischargev of clear fresh water or for use in the discharge of carbonated water.

A further objectis to provide a carbonll ator in which gas pressure is turned on voris effective during all of the periodof time that vthe valve is closed. i Other objects and advantages will be made manifest in the following specification y of an embodiment of the `invention illusaccompanying i drawings, whereinp Figure l is a plan of a carbonaltor,-the shell of which is shown in horizontal section. Fig. 2 is a verticalcentral section of the carbonator.

The present carbonator is shown as em` bodying any 'suitable form of insulated casing or jacket 2 preferably constructed to contain cooling water W up to any suitable level and this water may be occasionally drained off or replenished in any suitable manner. ln front of the casing 2 is arranged a mug or glass platform 3 and in this is arranged a small valve L1 having threeway ports so that excess liquid accumulating on the platform 3 may be drained straight down through a waste pipe 5. The drain valve or cock 41 is adapted to be turned to an angular position so as to communicate with a vduct 6 to the inner end of which is connected a Siphon pipe 7 terminating close is mounted a distributing to the bottom of the water containing casing 2. To drain the casing, 'it is only necessary to turn the valve 5 to such position as to communicate the duct 6 with the waste pipe 5 and the greater head of water in the casing 2 will cause itL to initiate a discharge through the pipe 7 and subsequently the water will be siphoned to the bottom of the casing.

Arrangedin the front of the casing and at a suitable distance above the glass platform 3 is a main draft valve body 10 having a downturned discharge spout or nozzle 9 andan inwardly projecting end 8 which is disposed in the upper portion of the casing 2.

In the lower portion of the casing there bottom of which may be provided with a drain cock V'12 and extending from the top of the distributing chamber is a centrally disposed pipe or tube v13 which, by my pres ent invention, serves gas and the dual functions of gas inlet means and a carbonated water outlet means; the upper endof the tube 13 being connected at 14 to the contiguous endV l of the draft valve body 10.

Secured to the inner end of thedraft valve body is a water pipe 15 preferably extended in the form of a helix 15a for convenience and compactness surroundingthe carbonated waterrtube 13. lower end of the water pipe is turned up` wardly at 15b and is connected to the bottom of ahead or water chamber 16.

V Gas distributing and baffling means are provided, and such means are here shown as comprising al series Iof vertically'er otherchamber 11, the

The

annees wise arranged columns 17 in the form of tubes having elbows 18 at their lower ends connected suitably as by unions 19 and nip ples 2O to the upper portion of the charnber 11 which is here shownv as ofspherical form. The upper ends of the carbonating columnsv 17 are also provided with elbows 21 connected as by unions 22 and nipples 23 to the lower portion of the water chamber 16 which is shown as spherical.

The apparatus provides for the initial cooling of the water in the water coil 15 before the water passes therefrom to the columns 17 wherein the water becomes saturated with the carboniol acid gas, and this precooling is obtained as by means of the water W in which may be submerged ice so as to keep the temperature of the water down tothat of iced water.

Gas which is supplied through'the gas pipe 13 passes from the distributing cham' ber 11 into the several uprightcol'amns 17, and for the purpose of increasing the area of contact between the descending streams of water flowing from the water head or chamber 16, meansl are provided in the gas colurnns to effect the diversion of the water and the gas into various circuitous passageways and against interposed baffles to cause the intimate contact of the gas and` water. A preferred form of bafllermeans is shown in detail in Figs. a to 8 inclusive in which there is shown a form of shelf or baille represented as a ring 25 having concaved sides and a central aperture 26 of relatively eonstricted area. A series of these baffle shelves is arranged in each of the columns v17, and between eachof the shelves there is disposed an intermediate barrier or baflle in the form of a disc 27 having convexed sides and which is herein termed a button.

Each disc is provided on its vupper and lower surfaces with a plurality of spacing lugs 28, the lugs of the lower faces rest-ing upon the next lower barrierand shelf forming` elements 25, while the lugs on the upper faces of the buttons 27 support the next higher shelf 25. The concave faces ofthe shelves 25 and the substantially concentric or parallel faces of the buttons 27 for-m constricted passageways vfrom bottom to top of the gas" columns andthus provide for a path of traverse of very considerable lengthV through which the gas ascendsv and the water descends and this insures the effective and rapid saturation of the water.

As clearly shown in Fig. 9, the draft valve f body 10 is provided on one side withY a nipple 30 for attachment of ar gas supply pipev 31 and on the other A'sideis provided with a nipple 32 vfor attachment of a fresh water' supply pipe 33. The nipple 31 is the ter-V minus' for a gas passage 30EL and the nipple 32 is the lterminus for a water passage *32a* isc which is shown in'Fig. 10 as being inv a lower plane than the gas passa-ge 30a, which latter terminates at its inner end contiguous to the tapered surface of a valve plug 35having rotative lit in a conical seat 36 provided therefor in the outer end of the valve body l0. The draft valve plug 35 is adapted to be operated as by means of a draft lever or handle 37, and the plug is constant-ly pressed to a liquid tight fit on its seat as by a. spring 38.

Paralleling the gaspassage 30L is a water passa-ge 40, the front end of which terminates contiguous to the valve plug 35 and to the rear end of which is connected theV water tube 15. In Fig. 10 the water passage 40 is shown as in vertical alinement with the water passage 32a so that a water port 41 provided in the valve plug 35 can be disposed, as shown in Fig. 14, to connect the water supply pipe 33 to the water supply passage 40. Concurrently with the setting of the water port 41 of the valve 35, as shown in Fig. 14, a discharge of carbonated water Vthrough the draft valve is provided for from the central tube 13. The outlet end of this tube is shown in Fig. 14 .as connected with a discharge passage 42 extending longitudinally through the valve body 1() and terminating in the valve seat 36 so that there can be registered with the carbonated water discharge passage 42, a discharge port 43 formed in the valve plug 35 and which, preferably, has a branched discharge end, the branches being shown at 43a and 43b which are adapted to register with outlet passages 44, provided in the spout of the draft valve body.

When the valve plug 35 is adjusted to provide for the discharge of carbonated water through the port 43 from the passage 42, there is at the same time a stream of fresh water being supplied through the port 41, as shown in the sketch in Fig. 14, the fresh water passing to the cooling coil tube 15.

A feature of the invention consists in providing for the supply of gas from the gas pipe 31 to the carbonated water conduit or passage 42; the gas supply passing from the pipe 31 to the gas passage 30a. The valve plug 35 is provided with a port 46 so formed and arranged that when the valve plug is in the cut-off or nondischarging position, Fig. 12, the gas port 46 will open communication from the gas passage 30a to the passage 42 and gas will then flow from the source of supply the gas bottle B, Fig. 3, to the lower distributing chamber 11.

The gas supplied to the chamber 11 will rise through the distributing and retarding columns 17 so as to charge the water therein and leaving the latter in readiness to be discharged by the movement of the valve handle 37 Vto its discharge position Shown in Fig. 1 4. L

It may be'desirable to obtain a discharge of the carbonated water in a fine froth o-r fizz stream, and in which' case the valve handle 37 n can be swung slightly so as to bring the discharge end 43b of the plu@ 43 over a central discharge aperture 45, *ign 16 this aperture being of comparatively small diameter and resulting in thel discharge of thercarbonated water in a line .adapted to move into register with the-passage 42 and with the central fizz discharge outlet 45. The air is discharged instantly while the port 48,- just described, isfcrossing the ends of the .passage 42 and the port45. To economize in the consumption, and -to avoid waste, of ycarbonio acid gases, I pro-I vide for the transfer of gas which may vcollect-inthe gas pipe 13 above the charged water therein back into the apparatus and preferably into the fresh water supply passageways, and for this purpose a cross duct 49, Fig. 13, is provided and this duct is designed to move into register with the outlet passage 42 momentarily and at` the same instant to register with the fresh water passage 32a thereby permitting the flow of the gas into the apparatus to be absorbed instead of escaping unused through the d 'ischarge spout.

It may be desirable, occasionally, to draw clear fresh water, uncarbonated, from the draft valve, and Fig. 15 shows the valve plug 35 positioned with its handle thrown rearwardly to the maximum degree at which time a port 50 in the valve is in communication with a water supply passage 32a and registers with the outlet 45 in the spout, thereby permitting the discharge of fresh water and at the same time interrupting free passage through the several remaining ports in the valve plug.

Further embodiments, modifications and changes may be resorted to within the spirit of the invention as here claimed.
